the height of the actual road sign is within an error range with the height of the road sign model, and the error exists in the height of the current actual road sign expressed by 'height difference'.
7. A road sign correction method according to claim 6, wherein in the analysis and evaluation based on the actual road sign construction,
and judging the construction condition of the actual road sign position by counting the occurrence times and proportion of the green model, the yellow model and the red model.
8. A road sign correction system based on a road sign correction method of any one of claims 1 to 7,
the system comprises a modeling module (1), a database module (2), a mapping module (3) and a detection module (4);
wherein the modeling module (1) is used for generating a road model and a road sign model;
the database module (2) stores preset information data of a road model and preset information data of a road sign model;
the mapping module (3) maps preset information data of the road model to the road model, and maps the preset information data of the road model to the road model;
the detection module (4) is used for detecting and identifying the road signs beside the road and acquiring actual data of the road signs;
the mapping module (3) replaces the actual data of the road signs with the preset information data of the road sign model, and the modeling module (1) generates a new road sign model.
9. A terminal comprising a memory, a processor and a computer program stored in the memory and capable of running on the processor, wherein the processor loads and executes the computer program, and wherein a roadmap correction method according to any one of claims 1-7 is used.
10. A computer-readable storage medium, in which a computer program is stored, which, when loaded and executed by a processor, implements a roadmap correction method as claimed in any one of claims 1 to 7.
